I am using an Asus A8N-SLI Deluxe M.B. with an Athlon 3800 processor.Windows XP on one hard drive and Vista Beta on the other.(Both ATA). I accidently hit the “suspend” button on the Logitech keyboard and put the system to sleep.Has not worked since ! Replaced the power supply and now turns on but no video.Also seems like H.D.’s are not spinning up.Keyboard does not seem to work also.No POST beeps even if I start the system with no mouse or keyboard. Also for video I am running a PCI-E video card. Dont know what else to try.Completely frustrated. Thanx in advance.
